ABSTRACT

A wind wheel assembly of a separable air conditioner which comprises the following components. A plurality of multi-sectional wind wheels is fixed to a seat of the separable air conditioners. At least one motor is positioned on at least one respective positioning plate, each motor being connected between two wind wheels. A plurality of bearings are positioned on at least one respective positioning plate; each bearing being positioned between two wind wheels or positioned at the outer side of two outermost wind wheels. The at least one motor and the plurality of bearing are alternatively arranged; thereby, the wind wheel assembly is operated smoothly and steadily.

FIELD OF THE INVENTION

[0001] The present invention relates to wind wheels, and particularly toa wind wheel assembly of a separable air conditioner which can operatessmoothly and steadily.

BACKGROUND OF THE INVENTION

[0002] In the prior art, the wind wheel is a single-sectional device.One end of the wind wheel is locked with a motor and another end of thewind wheel is locked to a bearing. However, this is induced that thewind wheel is too long to be operated smoothly and steadily. Moreover,for a longer operation time, since the wind wheel is too long so thatthe wind wheel will suspend downwards so that the lifetime of the windwheel is shortened. Moreover, the cool contraction and hot expansioneffect causes that the connection of the blades and the connectingsurface of the wind wheel will crack so that as the wind wheel operates,noise and vibration generate.

SUMMARY OF THE INVENTION

[0003] Accordingly, the primary object of the present invention is toprovide a wind wheel assembly of a separable air conditioner whichcomprises the following components.

[0004] A plurality of multi-sectional wind wheels is fixed to a seat;

[0005] At least one motor is positioned on at least one respectivepositioning plate, each motor being connected between two wind wheels;

[0006] At least one bearing is positioned on at least one respectivepositioning plate; each bearing being positioned between two wind wheelsor positioned at the outer side of two outermost wind wheels;

[0007] At least one motor and at least one bearing are alternativelyarranged; thereby, the wind wheel assembly being operated smoothly andsteadily.

[0008] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 1 to 4, the wind wheel assembly of a separableair conditioner of the present invention is illustrated. The presentinvention has two wind wheels (for example, the two sectional wind wheelshown in FIG. 1) or at least two wind wheel 10 (such as the threesectional wind wheel of FIG. 2), at least one positioning seats 20installed aside the case of an air conditioner, at least one positioningplate 30, at least two motors 40 and a plurality of bearings 50.

[0014] Two ends of the wind wheel 10 are constructed according to theconnecting elements, for example, motors 40 or bearings 50. If it theconnected to a motor 40, a toggle 11 is formed for enclosing a rotaryshaft 42 of the motor 40. An end surface of the toggle 11 has aplurality of screw holes so that screws 60 can pass through the screwholes 111 and a plurality of round holes 421 of the rotary shaft 42.Thereby, the end surface of the wind wheel 10 is connected to the motor40. If the connecting end of the wind wheel 10 is connected to thebearing 50. The connecting end is installed with an axial rod 13 whichserves to be inserted into an axial hole 51 of the bearing 50. Theconnecting end has an axial protruding axial rod cover 12 for beingengaged with the rotary shaft 422 of the motor 40. Then the studs 121 onthe axial rod cover 12 can be engaged with the rotary shaft 422.

[0015] The positioning seat 20 is installed with a groove 21 forengaging the bearing 50. When the bearing 50 is placed in the groove 21,a press plate 22 is locked and thus resists against the bearing 50.

[0016] The positioning plate 30 mainly serves for locking andpositioning the motor 40. The positioning plate 30 has a through hole131. When a rotary shaft 422 of the motor 40 passes through the throughhole 131, the shaft 422 can be locked in the axial rod cover 12. Aperiphery of the through hole 31 is installed with a plurality of viaholes 32 which are positioned with respect to the screw holes 412 at theend surface of the coil set 41 of the motor 40.

[0017] The motor 40 includes a coil set 41 and a rotary shaft set 42.The coil set 41 is formed with an axial penetrating hole 411. An endsurface of the coil set 41 for locking the positioning plate 30 areinstalled with a plurality of screw holes 412. The rotary shaft set 42is installed with an outer ring and a plurality of round holes 421 areformed at one end surface of the rotary shaft set 42. Thereby, when thewind wheel 10 is connected with the motor 40, screws 60 passes throughthe round holes 421 so as to fix the motor 40 (referring to FIG. 4).

[0018] By above mentioned components, the two section wind wheel 10 isused as an example. Referring to FIG. 1, one end surface of the windwheel 10 is locked with the motor 40 by screws 60 passing through thereceiving holes 421 of the motor 40 and then entering to the screw holes111 of the wind wheel 10. Thereby, the wind wheel 10 and the motor 40are connected as an integral body. Then, the screws lock the motor 40 tothe positioning plate 30 at the center of the seat 100. Then, the rotaryshaft 422 of the motor 40 protruded from the through hole 31 of thepositioning seats 20 is inserted into the axial rod cover 12 of anotherwind wheel 10. The studs 121 locks the motor 40. As a result, the axialrod 13 at another end of the wind wheel 10 is tightly inserted into theaxial hole 51 of the bearing 50. Thus, the bearings 50 are firmlysecured to the grooves 21 of the positioning seats 30 at two side of theseat 100.

[0019] In another embodiment of the present invention, a three-sectionalwind wheel is used as an example. Referring to FIG. 2, the assembly wayis approximately like above said way. The difference is that one end ofthe wind wheel 10 is connected to a motor 40 and another end of the windwheel 10 is connected to an independent bearing 50. Each wind wheel 10is driven by a motor 40.

[0020] From above said multi-sectional wind wheel 10, by the connectionof the motors 40 and the wind wheels 10, the wind wheel 10 can rotatesmoothly in equilibrium. Moreover, a larger wind is blown out and poweris saved with less noise.

[0021] The present invention is thus described, it will be obvious thatthe same may be varied in many ways. Such variations are not to beregarded as a departure from the spirit and scope of the presentinvention, and all such modifications as would be obvious to one skilledin the art are intended to be included within the scope of the followingclaims.
